⭐⭐⭐⭐⭐ Hello, I have carefully analyzed your calculator correction task and the requirements around offset account logic. I recently corrected front end loan calculators for Australian mortgage products, including P&I and interest only loans, where offset balances affected interest accrual, term reduction, and interest saved with exact amortization math. Your task is a precise, contained fix. I will adjust the existing HTML, CSS, and JavaScript logic to correctly apply offset balances to daily interest calculations, ensure interest saved is computed accurately, and ensure loan term reduction aligns with real bank amortization behavior. I will not rebuild or refactor beyond what is required, and I will self test the calculator thoroughly before joint validation. I am available to start immediately and can complete this within the stated one hour window on 18/01/26 AEST. I am fully confident working with bank lending, interest calculations, amortization, and offset mechanics, and will deliver mathematically exact results. Thank you, Benjamin
